Please answer the questions by filling out the blank on the right hand side of the table. To answer these questions, please follow the titanic example by installing install.packages("titanic") and then invoke library(titanic) in R. You should be able to get the same Analysis of Deviance table and logistic regression model and ROC curve. Please also open this stepwise logistic regression sample to learn how to use stepwise method for optimizing the logistic regression model. You can find details in Data Mining and Business Analytics with R Chapter 8 section 8.4 for ROC curve (found in this week's Reading
